BTW, the problem I'm having is that volume control does work Master, PCM and Front do the same and Headphones does not change that effect and plugging the headphones in does not stop front speakers from playing. Furthermore, headphone volume appears to be controlled by those other controls (instead of being changed by the Headphones one).

Re: SOLVED Headphone & Speaker Issue SOLVED

The point is, why this is not automatic when you plug the headphone?? This should be automatic, you plug the headphone and the built in speaker should be gone.

I have a dual boot, and I had the same problem in windows (it seems to be a Realtek sound card driver problem), I update the drivers and problem solved, but it does it automatically, you don't have to tilt anything, by just plug in the headphones it kills the built in speakers automatically.
